Luke 22:38

And in truth, if He wished them to use human aid, not a hundred swords would have sufficed; but if He willed not the assistance of man, even two are superfluous.

These things then God prophesied concerning what should befall the country of the Jews, but the disciples understood not the depth of His words, thinking they had need of swords against the coming attack of the traitor. Whence it follows; But they said, Lord, behold, here are two swords.

Or the two swords suffice for a testimony that Jesus suffered voluntarily. The one indeed was to teach the Apostles the presumption of their contending for their Lord, and His inherent virtue of healing; the other never taken out of its sheath, to show that they were not even permitted to do all that they could for His defence.

But He who forbids to strike, why does He order them to buy a sword? unless perchance that there may be a defence prepared, but no necessary retaliation; a seeming ability to be revenged, without the will. Hence it follows, And he who has not, (that is, a purse,) let him sell his garment, and buy a sword. Or, because the law does not forbid to return a blow, perhaps He says to Peter, as he is offering the two swords, It is enough, as though it were lawful until the Gospel; in order that there may be in the law, the knowledge of justice; in the Gospel, perfection of goodness. There is also a spiritual sword, that you may sell your patrimony, and buy the word, by which the nakedness of the soul is clothed. There is also a sword of suffering, so that you may strip your body, and with the spoils of your sacrificed flesh purchase for yourself the sacred crown of martyrdom. Again it moves, seeing that the disciples put forward two swords, whether perhaps one is not of the Old Testament, the other of the New, whereby we are armed against the wiles of the devil. Therefore the Lord says, It is enough, because he wanted nothing who is fortified by the teaching of both Testaments.

While they were contending among themselves above concerning priority, He saith, It is not a time of dignities, but rather of danger and slaughter. Behold I even your Master am led to a disgraceful death, to be reckoned with the transgressors. For these things which are prophesied of Me have an end, that is, a fulfilment. Wishing then to hint at a violent attack, He made mention of a sword, not altogether revealing it, lest they should be seized with dismay, nor did He entirely provide that they should not be shaken by these sudden attacks, but that afterwards recovering, they might marvel how He gave Himself up to the Passion, a ransom for the salvation of men. Or He hereby foretels to them that they would incur hunger and thirst, which He implies by the scrip, and sundry kinds of misery, which he intends by the sword. Our Lord then was unwilling to blame them as not understanding Him, but saying, It is enough, He dismissed them; as when we are addressing any one, and see that he does not understand what is said, we say, Well, let us leave him, lest we trouble him. But some say, that our Lord said, It is enough, ironically; as if He said, Since there are two swords, they will amply suffice against so large a multitude as is about to attack us.
